GRAIN-DRlLL.

, SPECIFICATION forming part of Letters-Patent No. 450,478, dated April 14, 1891.r Application filed September 8, 1890. Serial No. 364,371. (No model.)

To all whom it may concern.-

Be it known that we, ALTON L. BAUGHMAN and DELMER L. BAUGHMAN, both residents of Albion, in the county of Noble and State of Indiana, have invented certain new and useful Improvements in Grain-Drills; and we do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Our invention relates to improvements in grain-drills.

The object of the invention is to provide improved-means for causing the grain to be fed without variation in amount whether the drill is running straight or turning to the right or left, to provide means for throwing t-he feeding devices in and out of gear, to provide means for regulating the depth of drill, and to provide means for throwing the hoes into and out of line.

The invention also. contemplates other objects and advantages, which will be apparent to those skilled in the art to which the invention pertains.

The invention consists in the novel construction and combination of parts hereinafter fullT described, and specifically pointed out in the claims. K

In the accompanying drawings,Figure 1 is a plan view of a drill constructed in accordance with our invention,the wheels and hopper being removed. Fig. 2 is a side view of the same with the hopper in place. Fig. 3 is a sectional side elevation. Fig. at is a detail sectional view of the feed-wheel and cap, showing the position of the same in the hopper. Fig. 5 is an edge view of the feed-wheel. Fig. 6 is a rear view showing two grain-spouts coupled to a cup. Fig. 7 is a view of a portion of the hopper and the feed-shaft gears. Fig. 8 is an inside view of the hub of the loose driving-wheel, showing its pawl and the ratchet on the rotating sleeve.' Fig. 9 is an inside view of one of the feed-wheel caps or cups. Fig. l is a detail view of a portion of one of the feed-wheels. Figs. 1l and l2 are detail views of the bearing for the shaft carrying the gear for operating the feed-wheel shaft. Fig. 12S-isa detail view of the segment at the rear of the machine.

In the said drawings the frame of the drill is shown as being composed of side bars l and transverse bar 2 and provided with a tongue 3.

The numeral 4 designates the axle which supports the driving-wheels and 6, the drivin g-wh eel 5 being iixed to the axle and revolving therewith, the axle at this side of the drill being journaled in a bearing 7 in the frame 1. At the opposite end the axle is provided with a sleeve 8, which revolves freely thereon and which passes through the hub of the d1iving-wheelG,its end being received in a collar 9, secured in the end of the axle.

Intermediate of theinner side of the wheelhub and the drill-frame and formed integral rwi th sleeve 8 are the cog-wheel l0 and ratchetwheel l2, the former of which meshes with a gear-wheel 13 on a shaft 14, while the ratchetwheel engages with a pawl 15, secured t'o or connected with the wheel-hub, so that as said wheel revolves the gear 13 also revolves, so as to rotate the shaft 14 and, through the medium of the gears l-i" and 14,, rotate the feedshaft and the feed-wheels and arms, as will hereinafter be described. The sleeve S extends through the side bar l of the frame and at its inner end is provided with a ratchetwheel 17, fixed .thereto or formed integral therewith.

The numeral 18 designates a collar secured to the axle and abutting against ratchet 17 and carries a pawl 19 to engage with said ratchet to revolve the Sleeve and actuate the feed-wheels when the axle revolves and the wheel G does not rotate-as, for instance,\vhen turning.

The end of the shaft 14 which carries the cog-wheel 13 is journaled in a frame or casing 20, pivoted to an arm secured to the hopper, said frame having a rearwardly-extending arm 21, the end of which engages with a shoulder 22 on the upper end of a lever 23, pivoted in a bearing 24, secured to the side bar of the drill. The object of this lever 23 is to hold the gear 13 in mesh with cog-wheel and prevent its displacement until thrown out of gear, as hereinafter explained, being provided with a coiled spring.23 for such purposes. The lower end of the lever 23 is provided with a stud 25, which engages with ICO ordinary construction, secured to the drillframein the usual manner, and at its reari side near the bottom is the transverse feedshaft 34, having at one end the gear 1l,`

which meshes with gear 1t on shaft 1t.

At suitable intervals in the rear side of the hopperare the feed-wheel caps or cups 35, having openings in cach side. "lhe feed-shaft 3l passes through these caps and carries the feed-wheels 37, each of which consists of a central disk having a series ot` curved radial l wings or ribs 38 on each face. "lhe periphery of this disk extends beyond the ends of the wings or ribs, forming an annular flange 39, which lits in a similarly-shaped groove l0 in the cap 35, which will prevent the grain from getting between the disks and caps and becoming crushed and thus unlit tor use. ln the lower part ot` each cap is a lug t1, through which passes a pivot-pin l2, which carries the feed-spouts 43, one on each side ot the caps.

These spouis are provided with the usual feed-tubes 4l, of rubber or other similar material, which pass down through the ordinary teeth 45. It will thus he seen that one teedwheel serves to feed the grain from the hopper to two delivery-tubes.

The teeth 45 at their upper ends are provided with forwardly-extending projections 46, each having a series ot' orifices t7, with which are connected the drag-bars t8. These drag-bars are bifurcated at their forward ends and are alternately connected with the transverse eccentrically-journaled bars -lQ and 50, mounted in the side bars lot' the drill-frame. At one end of the rear bar if) is secured a lcver 52, which is connected by means of `a link with a crank 54, secured to bar 50. 'lhe free end of lever 52 is connected with a rearwardly-extending bar 55, having a handle 56 and provided on its under side with a series of notches 57, which engage with a lug 59, secured to the hopper. By operating the bar 55 the transverse bars will be oscillated so as to bring` their lower portions which carry the d rag-bars nearer to or farther from each other, and thus causing theteeth to lie in a straight or zigzag line, as will be obvious.

The teeth are supported at the rear by means of chains 45 or adjustable arms secured thereto and to one end ot' the levers (50, secu red to collars 6l, which embrace and work loosely on the rock-bar 29. These levers also have backward extensions 152, by which they maybe operated to regulate the depth of drilling. This rock-bar 29 is journaled in bearings in the side trarne 1. The numeral 63 designates a segment-plate, the forward end ot' which is secured to a beam or tongue 3, secured to the central cross-bar 2 ot the drilltrame, and at its rear is formed with a series ot' ratchet-teeth (AS-l, with which the springpawl .55 et' the lever 6G engages. This lever is tirnily secured to the rock-bar 39 and has a forwardly-extending arm 67, having a hooked end, which engages with a transverse bar |38, [see Fig. 1,) connected at each end with the rock-bar 2t). This bar GS lies a little in t'rontot" and below the bar 29 and is immediately underneath the front arms of the levers 130, so that as it is raised by lever 156 and bar 2) it will raise-the front ends of levers 50 and elevate the teeth, so as to regulate the depth ot' drill.

"l`he operation is as follows: As the drill moves forward the wheels 5 and fi and the axle will revolve, Causing the sleeve S, carrying the cog-wheel 10, to be rotated by means ot' the ratchet-wheels 12 and 17, engaging, respectively, with the pawls 15 and 19 on the hub of wheel G and on the axle. The revolution of cog 10 rotates gear 13 on shaft 1l,and through the medium of gears 1l and ll" the feed-shaft and feed-wheels are rotated. lVhen it is desired to turn the drill, say, to the left, with wheel 5 as a center, then this wheel and the axle to which it is fixed will not rotate. lVheel V, however, will revolve, and by means ot the pawl l5 and ratchet 12 the sleeve S, upon which it is journaled, will revolve and the feed be kept up through the medium of gear 13 and connections. In turning in the opposite direction or to the right then wheel t3 will not revolve; but wheel 5 and the axle will rotate, and by means of the ratchet 17 and pawl 19 on the axle the said sleeve 8 will continue to revolve and the feed-wheels to be actuated. llt will thus be seen that the feed is continuous, whether the machine be running ahead or turning either to the right or to the left.

"lhe teeth may be elevated or depressed to f regulate the depth of drill either singly or collectively, as desired. To adjust them singly, it is simply necessary to elevate or depress the rear extensions of the levers 60, as betere set fort-h. To adjust the teeth collectively or sim ultaneously,the lever G6 is pushed backward, which will actuate the rock-bar 29, causing the bar GS, with which itis connected, to be raised, which in turn will raise the front arms of levers G0, and consequently the teeth, through the chain with which they are connected to said levers. The pawl carried by lever 66 will engage with the ratchet-teeth ot the segment-plate 63 and retain the teeth in their adjusted positions. To depress the teeth to drill deeper, the lever 6G is released, when the bars and teeth Will drop by gravity.

To throw the gears 10 and 13 out of mesh, so as to stop movement of the feed-wheels, the lever 66 is pushed still farther back toward the last notch in the segment-plate 63. This will cause the reciprocating bar 27 to be pushed forward until the stud 31 of the downWardly-depending arm will strike the end of slot 30, causing the vframe 2O to be raised and the gear 13 to be thrown out of mesh with cog 10. At the same time the stud 25 will come in contact with the end of slot 26, causing lever 23 to turn on its pivot and the arm 21 of frame 2O to be released from the shoulder 24, so as to alloW said frame to turn on its pivot. To throw into gear again, the lever 66 is released and the bar 27 drawn back, when the forward end of frame 2O will drop down bygravity, so as to bring gear 13 and cog into mesh. At the same time lever 23 would be thrown into position by means of its coiled spring 23% This lever also prevents breakage of the teeth of the gears 10 and 13 by preventing gear 13 from' striking cog 10 until in position to properly mesh therewith.

In Figs. 11 and 12 We have shown an adjustable bearing for the shaft 14, the same consisting of a plate or bar 60, havinga head 70, provided with a circular bore, through which the said shaft. passes. This plate is also provided with a longitudinal slot 71, through which passes a bolt '7 2, provided with a thumb-nut 7 3. This bolt also passes through thecasting 75, which supports the hopper. It will be obvious that the plate may be adj usted longitudinally by means of the thumbscrew and bolt.

The gear 14D on the shaft 14 is provided with a flange 14C, which abuts against the inner side of the gear 14n, thus obviating the use of pins to secure the same to its shaft, as the ange Will prevent its displacement until gear 14 is removed.

Having thus described our invention, what we claim is- 1. In a grain-drill, the combination, with the frame, an axle having a paWl intermediate of its ends, and a driving or supporting wheel fixed to one end of the axle, of a sleeve loosely mounted upon theother end of the axle, and a driving or supporting Wheel having a pawl journaled on said sleeve, the sleeve being provided with ratchet-Wheels at each end engaging, respectively, with the pawls on the axle and wheel, substantially as described.

2. In a grain-drill, the combination, with the frame, an axle having a paWl intermediate of its ends, and a driving or supporting Wheel tixed to one end of the axle, of a sleeve loosely mounted upon the other end of the axle, a driving or supporting Wheel having a pawl journaled on said sleeve, the sleeve being provided with ratchet-Wheels at each end engaging, respectively, with the pawls on the axle and Wheel and an intermediate cog- Wheel, a transverse shaft having gears, one end ot which meshes With the cog on the sleeve, and afeed-bar having feed-wheels and a gear meshing with the other gear on the transverse shaft, substantially as described.

3. In a grain-drill, the combination, Wit-h the frame, the axle, the supporting-Wheels, and the teeth,'of a transverse rock-bar 29, located in the rear of the frame, a transverse bar 63, connected With said rock-bar and 1ocated in front thereof, a series of levers 60, pivoted on the rock-bar and connected with the teeth, a lever 66, secured tov the rock-bar 29, having a hooked end 67 engaging with the bar GS, and means for locking the lever in position, substantially as described.

4. In a grain-drill, the combination, with the frame, the axle, the supporting or driving Wheels, and a cog-Wheel driven by said Wheels, oi' a pivoted frame carrying a transverse bar having a gear meshing with said cog-wheel, said frame being provided with a downwardly-extending arm and a rearwardly-extendin g arm, a pivoted spring-lever having a shoulder engaging With said rearwardly-extending arm7 a reciprocating bar having slots with which studs on said arms engage, and a rock-bar having an operating-lever and a crank connected With the reciprocating bar,
